Abstract

The paper investigates general properties of the power series over a non- Archimedean ordered field, extending to the set of algebraic power series the intermediate value theorem and Rolle's theorem and proving that  an algebraic series attains its maximum and its minimum in every closed interval.

The paper also investigates a few properties concerning the convergence of power
series, Taylor's expansion around a point and the order of a zero.
